Abstract

There is provided a granular, silicate-built, phosphate free laundry detergent composition comprising fine alkali metal percarbonate particles having mean particle diameter below 450 mu m, preferably below 400 mu m, wherein no more than 20%, preferably no more than 10%, of the particles have a diameter above 710 mu m, said particles having a coating comprising one or more soluble inorganic salts. The salts may be selected from alkali or alkaline earth metal carbonates, sulphates, chlorides and nitrates. The coated percarbonate particles have improved stability to storage and are capable of dissolving quickly in wash liquor.
